generation.
(hppaosf_finish, hppaosf_search_for_padding_statements,
hppaosf_create_output_section_statements): New functions in
support of linker stub generation.
(ld_hppaosf_emulation): Redefine to include new
emulation-specific routines.
(open_output): Set it after bfd open succeeds.
* ldmisc.c (vfinfo): Test it.
Changes from Peter Hoogenboom, hoogen@cs.utah.edu:
* ldsym.c (write_file_locals): Set the BSF_FILE flag for object symbols.
* ldemul.c: Support was added to allow emulation-specific processing to occur.
This support was added primarily for linker stub generation in the elf32-hppa
gld.
(ldemul_finish, ldemul_create_output_section_statements): New functions.
* ldemul.h: Support was added to allow emulation-specific processing to occur.
(As described above.) Added finish and create_output_section_statements fields
to ld_emulation_xfer_struct structure.
* ldlang.c: Add calls to emulation-specific routines.
(lang_process): Add call to ldemul_create_output_section_statements function.
(lang_process): Add call to a emulation-specific routine (and
some processing after the call).
* Makefile.in (ALL_EMULATIONS): Added em_alpha.o.
(em_alpha.c): New target; use alpha.sh and alpha.sc.
* config/alphaosf.mh (NATIVE_LIB_DIRS, HOSTING_CRT0): Define.
* config/alpha.mt: New file.
* emulparams/alpha.sh: New file.
* scripttempl/alpha.sc: New file.
* scripttempl/elf.sc: Only use OTHER_READONLY_SECTIONS and
OTHER_READWRITE_SECTIONS if relocating. Shell variables are not
expanded within them.
* config/mipsb-elf32.mt: New file.
* emulparams/elf32mipb.sh: New file.
* Makefile.in (em_elf32mipb.c): New target.
INPUT(), then change the file type to lang_input_file_is_l_enum.
* ldgram.y: In input_list, change lang_input_file_is_file_enum to
lang_input_file_is_search_file_enum so objects brought in using
INPUT() do a path lookup.
* ld.h (flag_is_weak): Define.
* ldlang.c (print_symbol): Mention whether symbol is weak.
(print_input_section): Print weak symbols as globals.
* ldmain.c (refize): Do not zero out BSF_WEAK flag.
(enter_global_ref): Do not warn if a weak symbol redefines a
global symbol. Do not let a weak symbol redefine a common symbol.
(enter_file_symbols): Treat weak symbols as global symbols.
(subfile_wanted_p): Do not pull in an object file from a archive
just to resolve an undefined weak symbol.
* ldmisc.c (vfinfo): Don't needlessly malloc space after a fatal
error; the error might be that malloc has run out of space.
* ldsym.c (write_file_locals): Treat weak symbols as global.
* configure.in (i[34]86-*-sysv4*, i[34]86-*-elf*): New targets;
use i386-elf.
* config/i386v4.mh: New file; set NATIVE_LIB_DIRS to /usr/ccs/lib.
* config/i386-elf.mt: New file; set EMUL to elf_i386.
* emulparams/elf_i386.sh: New file.
* scripttempl/elf.sc: Use ${NOP} as filler (defaults to 0).
* Makefile.in (NATIVE_LIB_DIRS): Define to be empty.
(ALL_EMULATIONS): Add em_elf_i386.o.
(GENSCRIPTS): Pass NATIVE_LIB_DIRS as sixth argument.
(em_elf_i386.c): New target, like other em_*.c targets.
($(LD_PROG)): Pass $(CFLAGS) to $(CC).
* genscripts.sh: Accept NATIVE_LIB_DIRS as sixth argument. If
nonempty, and configured for native, add it to LIB_PATH.
* emultempl/hppaosf.em (ld_hppaosf_emulation): Correct name for PA
ELF emulation is "elf32-hppa" not "elf-big".
(hppaosf_before_parse): Remove unneeded processing of environment variables.
* scripttempl/hppaosf.sc: Include .hppa_linker_stubs sections in
.text segment of output file.
* emulparams/hppaosf.sh (OUTPUT_FORMAT): Use elf32-hppa.
